I have 3 different meters and have checked my blood sugar with all 3 at the same time and get 3 different readings with a difference of up to 60 points. What's up with this? how do I know which one is right? 60 points is a huge spread.. I am due for surgery and have already been postponed due to high sugar once so it's important to get sugar straightened out now..

Decide on one you like and just use that one … I have maybe ten meters collected and used over the years … I only use one now and have one identical as back up … I would recommend you just check with one and keep using that one …

I’m no expert, but what I learned here is that all meters have up to a 20% error factor.
I also learned that I can get up to a 10 point difference from the same drop of blood.
Also learned that your blood sugar isn’t always consistently mixed as it runs through your body.
I’ve also tested rapid-fire on 5 different fingers and got a 20 point spread. Check that out in this thread
As a very anal-retentive person this drove me nuts. I’ve since learned to live with the “error margin” as a ball-park, and only start reacting when I see things over 170 or below 60. I only use one meter as well.
A 60 point spread though sounds like you’ve experienced just about everything that can be off.

I have a One Touch Ultra, and a CVS Truetrak. Sometimes they are only 5 points apart, sometimes they are 25 or more. I have no idea how they can be so far apart. I'm hoping an expert answers your question!

I have been sticking my fingers for twenty years, and so as not to be redundant, I'll just say I agree with Nick1962. There are numerous links written by professionals that explain there is a +/- 20% margin of error built into most meters. Some of the instruction manuals even state it in their directions. The FDA also allows this percentage of error, although it may be changing. Bottom line, it's simply a helpful tool to keep you in the ballpark. You still need to be tested by a doc and laboratory.
